During embryogenesis the heart forms as a linear tube that then undergoes multiple simultaneous morphogenetic events to obtain its mature shape. To understand the gene regulatory networks (GRNs) driving this phase of heart development, during which many congenital heart disease malformations likely arise, we conducted an RNA-seq timecourse in zebrafish from 30 hpf to 72 hpf and identified 5861 genes with altered expression. We clustered the genes by temporal expression pattern, identified transcription factor binding motifs enriched in each cluster, and generated a model GRN for the major gene batteries in heart morphogenesis.

View SamplesSexual differentiation in zebrafish is complex. Although zebrafish sex determination is primarily genetic, hormonal and environmental factors can influence sexual development. 17 alpha-methyltestosterone (MT), a synthetic androgen, induces female-to-male sex reversal in zebrafish. MT treatment is routinely used in aquaculture for production of all-male populations. However, the molecular mechanisms underlying 17 alpha-methyltestosterone induced gonad masculinisation in fish are poorly understood.In this study, we analysed gonad transcriptomes of zebrafish treated with 17 alpha-methyltestosterone during gonadal development (from 20 dpf to 40 dpf and 60 dpf) and compared them with testis and ovary transcriptomes of untreated zebrafish. These data improve our understanding of the role of androgens in teleost sex differentiation.

View SamplesThis project aims to identify genes that are differentially expressed by premyelinating oligodendrocytes in the absence of transcription factor EB (TFEB). Premyelinating oligodendrocytes were acutely purified by immunopanning approach from P12 Olig2-Cre; TFEB F/+ or P12 Olig2-Cre; TFEB F/F mouse brains. Bulk sequencing were performed with 4 biological replicates per genotype.

View SamplesNuclear reprogramming is an inefficient process with only a small proportion of cells successful converting into induced pluripotent stem (iPS) cells. However, in order to molecularly understand the process these rare intermediates need to be identified and isolated for profiling. In the context of this project we purified the rare reprogramming for three cell types (Fibroblasts, Neutrophils and Keratinocytes) by fluorescent activated cell sorting and submitted them, together with the resulting iPS cells, to RNA sequencing.

View SamplesLhx5 mutant mouse embryos show loss of a neuronal nucleus of the brain called the mamillary body and essential for the formation of memories. We wanted to identify the genes that are responsible for the normal development of the mammillary body.
